What is the reason for children's blood in stool

When a child has blood in his stool, it sounds very serious at first. There are many reasons for blood in the stool. As a parent, first of all, don't be anxious. Check in time so that you can carry out symptomatic treatment and conditioning. Some cases of blood in the stool are caused by improper conditioning in life. For example, during breastfeeding, the mother's nipples may ulcerate when the child is breastfeeding, and the child may eat the blood that flows out, which will cause symptoms that look like blood in the stool. In addition, children taking some iron supplements may also easily develop such symptoms.

1. Taking iron supplements (iron foods)

If a child takes a multivitamin preparation or iron supplement containing iron, not all of the iron will be absorbed and a small amount will be excreted through the intestines. At this time, the stool may contain dark brown spots, and the fecal occult blood will be positive. This is the case with Qiuqiu in the first example, because the doctor learned after questioning that Qiuqiu had been taking iron-containing multivitamins (vitamin foods) every day since he was 6 months old. This condition has nothing to do with the child's intestinal development or disease. As long as the child grows normally, there is no need to worry.

2. Damage to the small intestinal mucosa

If the small intestinal mucosa is damaged, the stool will also contain red substances and the stool test for occult blood will be positive. Accidental ingestion of medications or foreign objects can cause damage to the intestinal mucosa, but for young babies (baby food), this possibility is very small. Most intestinal damage is caused by food, the most common of which is milk. The intestines cannot tolerate certain foods, causing damage to the small intestinal mucosa and blood to enter the intestinal cavity. Since the blood stays in the intestine for a while before being excreted with the stool, it will be destroyed by the intestinal fluid during this period. Therefore, stool testing can only detect occult blood in the stool, but no red blood cells. However, this small intestinal damage can persist without a change in diet, causing the child to have slowed growth and development. This is the case with Qiangqiang in the second example. After Qiangqiang was born, he was mainly fed with infant formula and developed an intolerance to milk protein. After converting amino acids (amino acid food) and deeply hydrolyzed special formula powder, Qiangqiang's bowel movements returned to normal and his growth also quickly returned to normal.

3. Disinfectants damage the intestines

Some chemicals, especially disinfectants, can also cause damage to the intestinal mucosa, as is the case with Xiaodong in the third example. Parents believe that disinfection can keep children away from germs, but the children's chances of being exposed to disinfectants have also increased significantly. Over time, chronic ingestion of disinfectants has become the culprit of intestinal damage. After that, the parents used clean water instead of disinfectant wipes, and the child's bowel movements soon returned to normal.

4. Anal fissure

If fresh blood is visible in the stool and the blood is attached to the surface of the stool, and examination shows the presence of red blood cells, it is mostly caused by anal fissure. As mentioned in the fourth example, the child will cry and have difficulty defecating, but the stool may not necessarily be dry and hard. Because the anal sphincter of infants is not fully developed and the coordination of contraction and relaxation is not perfect, small cracks often occur during defecation, resulting in a small amount of blood in the stool. At this time, apply a small amount of antibiotic ointment on the anus and the condition will soon improve.
